To all whom it may concern: i

' Be it known that I, WOLF ARBETTER, 'a' citizen of the United States,and a resident of Chelsea, in the county of Suffolk and State ofMassachusetts, have invented an Improvement inAttachments forBlindstitch Sewing- Machines, of which the following description, inconnection With the accompanying draw-. ings, is. aspecification likecharacters on the drawings representing like parts. Thisinvention hasfor its object the production of a machine especially devised forfelling facings or linings onto waistbarlgdSafter the buttons have beenstitched inplace thereon, thus enabling this class of work,,

which has alwaysbeen done by hand, to be done by machinery. v

Figure 1 in front elevation shows asufficient art or a sewing machine,such as illustrate in application, Serial No. 227 ,2'1 8, filed October5, 1904, with my improvement added to enable my invention to be de--scribed. Fig.2 isa right-hand side elevation of the parts shown nFigL-lL Fig. 3 is a top or plan view. Fig. 4 is a rear side view of theparts shown inllig. 1, and 5 shows a plan and end view. of thepresser-foot detached. v t

In the drawings, A represents part of the framework ofv the machine, it

feed-actuating shaft'Dt, said shaft, the feed cam D thereon, the ieedingdevice E, pro.-

as usual The waistband is always provided with buttons, which areattached to the body thereof by hand prior to stitchin the facing thefacing to be stitched to the band bile ma;- chine a space must beprovided t ough which the r uttons may travel and not interfere wltllthe stitching operation, It will be. understood that it is necessary forthe -matetdthe waistband, and consequent y to enable rial acted upon bythe feed and passing'between the cloth-plate and the presserfoot to 1 bemoved in a straight line, anda button could not come between theresser-foot and the Work-su port Without destroyin the op-' eration of te machine; Instead,-.t erefore,

of the work-support shown'in said appl1ca' tion I haveprovidedawork-support composed of a main plate 200' and an auxiliary 7 7plate 202, the edges of the plate being so 10- cated with relation oneto the other as to re-x' sent a button passage-way or slot 201. he slot201 is open in the direction of the length of the feed, (preferablyshown inrFig; 2,) and the buttons travel below the work-support as' thefeeding'device 5, in'engagement with the work, moves the same over thework-sup-V port, ,the'edges of -the main and auxiliary the space betweenthe buttons and waist and in the line ofthe attach; ment of the buttonsto said waistband and close to the stitches employed to connect thebuttons to the Waistband. 4 p

The work-sup ort sustainsthe waistband at each side the ine in which thebuttons are attached thereto. The Work-support has a slot in which movesthe serrated upper end 5 v of the feeding device, it engaging the outerside of the waistband near its top edge, or thatpart of the waistb'andabove the line of buttons when the-pantaloons are being worn, said edgebeing guided by contact with'an edge-gage 2'04, (sho wn as occupying itsopeffiative position above the'work-su port,) the acting edge of saidgage being su stantially 1 "opposite the point where the (hint of theneedle enters the inturned'or f0 ded edge w of the waistband or facinw,-which-folded I h by the needle a and stitched" to the waistband b theneedlethread and the com lenientarythread device, shown as a loo -ta ercontaining a bobbincase having a {obbin in which is a second roo 1thread} all as providedf or in said application .and also in UnitedStates Patent N 0. 690,385,

' said shank. The lower end of the shank dated January 7, 1902,. andgranted to me.

, The edge=gage is carried at the-up or end,

of a shank 205, provided below sai worksupport with a spring 206, thelower end of the spring being shown as resting on a pin in rests on agage-controller 207, shown as a lever pivoted at 208 and having acam-shaped end 209. When the controller stands in the Position shown inthe drawings, the gage is fted into its operative position; but whenturned into the dotted-line position, Fig. 3,

thespringreferred to retracts the gage into its inoperative position,said gage being then- Withdrawn, so that its top is substantially thefacing to Within about an inch or so flush with the work snpport, saidgage occupying its ino erative posit-ion when the st itching has beencarried along the upper edge of from the front end of the waistband,where the fac- I with the inner edge of the usual buttonhole.

.in'g ends andwhere the line of stitching is to be then carried acrossthe end of the facin and across the'waistband and down paralle iece orfly; Withdrawing the edge-gage, as

escribed, permits the position of the workto be changed shat ly aboutthe needle that the work may be te in a direction at right angles to thedirection in which it was being fed when the edge of the Waistbandcontacted with the edge-gage.

During the stitching of the infolded edge of the material or facing w tothe waistbandsaid edge will run against the guiding-edge 2100f theresser-foot, (herein marked D,)

v which differs somewhat from the presser foot ofsaid application. Thepresser=foothas an overhanging lip 212, provided Witha finger 213,,thatis extended forwardly, one side of said finger-forming a continuation ofthe edge-gage 210-. The resser-f'o'ot has a crossslot 214to receive tsedge-gage 204 when the latter occupies its "operative position abovethe 'wo'rk-su slot 214 theheel215 of the Presser-foot is provided at itsupper side with an inwardlg- "tapering groove 216-, said" oove and t Ithrusaent'ering 'fold groove 21-7 in the top of the out part of theresser-foot receiving the curved needle as it approaches the 'materialthat its point mayenter' the ni'aterial '10 passing under thepresser-footbt one thrust, a bender, fully des scribed in saidapplication, being then, raised and at the next t rust, which is adiagonal the edge 10' of the materialw. the Presser-foot has a wingprojects (see Fig, 1) beyond the Thebot-tom o 218-, that edge w of thefacing from; contact with the material it)", thus enabling the underside of the infold'ed material to travel over said out of contact withthe mate rialw" as the material to be stitched is being .overla the inolded edge of the material w down on port.

The rear part of the Presser-foot has a'forwardly-projecting toe 219, that somewhat the end ,of the wing 218 andretains the endof the wing during the action ofthe needle.
